Recorded caveats
- Wall-clock and API duration are whole-minute values displayed by the provider, not raw timestamps.
- The displayed input, cache, and output values are abbreviated; the recorded 92,558,400 processed-token total is an approximation from those displayed components.
- The $30.17 total is provider-reported and is not a verified API-equivalent cost calculation.
- The supplied report does not establish one-shot protocol compliance or session-specific assistant/model-call counts.
- Rolling local-activity requests are excluded because they are not session-attributed benchmark metrics.
- Static syntax/serve success does not establish runtime interaction, WebGL visual fidelity to the reference frames, audio, local FPS, RTX capture, or blind-vote outcomes.
- The supplied usage report does not provide user-turn, assistant-turn, or raw transcript evidence.
Visible evidence gaps
- raw Claude Code session export or exact machine-readable token receipt
- per-line pricing and cache-TTL receipt sufficient to recompute cost
- recorded one-shot protocol evidence
- browser interaction, keyboard navigation, and QUIT-state replay receipt
- reference-state candidate captures
- local FPS with browser, hardware, and viewport receipt
- RTX final capture
- blind-evaluation record
